Tung Chee-hwa has been accused of using his special adviser to investigate human rights groups. A few weeks before the consultative document on proposals to amend laws of freedom of assembly and association was published, a researcher from the Hong Kong Policy Research Institute called up human rights groups to inquire about their structure, activities and, in particular, registration details. The institute was founded by Paul Yip Kwok-wah, Mr Tung's special adviser. According to Human Rights Watch Asia, researcher Adith Wong said the institute was looking into human rights groups but declined to say who had commissioned the study, citing business confidentiality. Ms Wong was given the group's reports and pamphlets. She then sent a fax to ask whether the body was registered as a company or a society. The group is a limited company. Ms Wong said the inquiry was nothing more than a regular update of the database. The director of the institute, Dr Jane Lee Ching-yee, refused to comment. Robin Munro, director of Human Rights Watch Asia, said: 'It is obvious that the inquiry exercise is connected with the consultative document and that they are doing investigation for the chief executive.' Human Rights Monitor and the Information Centre of Human Rights and Democratic Movements in China, founded as societies, were also contacted.
